Get it Here

1) - Brian and Justin aren't together. J is in NY. The bouncer at the club he goes to is a really big, ugly guy who becomes friends with J. It turns out he was a world winner in boxer. J dyes his hair black, as his roommate gets him into drugs and goth. J shows back up in Pittsburgh for Jennifer's funeral, and that's the first time Brian and Debbie are aware he's in troube. Brian insists on driving Justin to the train station, who in turn runs away from Brian. Later in the story Justin comes back to Pittsburgh and Brian gets Justin's big friend to be his companion.

2) - I don't remember too many details about this one, but Brian is someplace (I believe he's not in Pittsburgh)  and goes club hopping. His driver is suppose to keep an eye on him, but Brian connects with two shady men in the bar, and gets them to help him leave out the back door. From there they take him to an dive bar and they get him some drugs. When Brian insists on leaving, the men follow him outside and attack him. They cut his leather jacket off him, and possibly his clothes, and end up raping him by this dumpster in the back of the bar.

3) - Brian and Justin move into Britin. Justin's lonely, so Brian encourages him to paint the walls. The walls come alive from being painted. They constantly whisper to Justin, until Justin goes crazy, and ends up killing Brian.  (Short Story.)

4) - Again a fic at Britin. Justin gets sucked into a mirror in the attic. Brian goes out of his mind trying to find him. I'm "thinking" he might have called in Mysterious Marilyn to help him get Justin back. I think it ends with them throwing a sheet over the mirror. (Another short story,)

THANK YOU FOR ANY HELP!  IT'S MUCH APPRECIATED!
